Would it be possible for this to happen?

If you check the Episode 2 "Lizards" forum you will find a thread similar to this that I made.

Nathan is Claire's direct father, but there is a possible relation. Though most people on the forums disagree with it. I got a lot of dribble and harassment for my thread

Even the writers commented to a similiar question..

They said that there is no relation between the people who have the same powers..

In answer to your question, "Kensei, Claire's Father?", no, Nathan = Claire's father.

Agreed. Also, Claire's new guy at school can fly so if he was related to Nathan then Claire would be french kissing a relative!

And you can assume that the writers would never do that... that would just be too shocking for the public making it seem that its okay to french kiss a relative.
So West and Nathan being relative = no way... 100% untrue
Kensei being relative to Claire ... = 99% untrue

Theres no proof that abilities are inherited...and so far it hasnt happened, and basically the abilites are farfetched from thier parents abilities.

So i highly doubt shes related
just same ability

totally agreed with u there Uker

Agreed.

Try not to have one word posts please and go to the episode 2 subforum to discuss this
